The global population is growing, human beings are becoming more civilized. The growing population is calling for expansion in settlement, food security, good transport and infrastructural development, mechanized equipment and sophisticated digital technology to meet the demands of the day. But for all this to happen, the world needs Energy and not just any other, but an energy source collected from renewable resources which are naturally replenished or rather sustainable on a human timescale, energy reffered to as renewable energy.

Energy is so cruicial to the progress of mankind starting from household level to global scale. Since hundred years past, human beings have been successful on discovering various sources of energy and some have been useful to our planet while other energy sources like coal and crude oil have brought more harm than good to our planet.

It is for such reasons that the focus of the world today has changed from not only discovering sources of energy to power the planet, but also to ensure the world is propelled by energy sources that are green clean and sustainable or just simply renewable energy.

An example of renewable energy is Biogas. Most literature, Biogas is described as a type of biofuel that is naturally produced from the decomposition of organic waste. Such organic matter may include food scraps and animal waste. They can be broken down in an environment absent of oxygen and they will release a blend of gases, primarily methane and carbon dioxide. 

From such blend of gasses, energy is produced good enough to be used at both industrial and household levels. The variety of organic matter used to produce Biogas is one reason for this diversity of models for biogas digesters and applications. Biogas energy has been successful in industrial systems that are  designed to treat: municipal wastewater, industrial wastewater, municipal solid waste, and agricultural waste.

On small-scale systemsused for digesting animal waste. And newer family-size systems are designed to digest food waste. The resulting biogas can be used in several ways including: gas, electricity, heat, and transportation fuels.

 Biogas is one renewable source which when implemented can be great entrepreneurship opportunity for youths to produce and sell energy that is green clean and sustainable. Households can also utilise biogas from the organic waste for instance sewer systems or kitchen waste. Such energy can help them light their homes, cook and generally reduce on electricity tarrifs.

Renewable energy is the future. Let us utilise whatever opportunity there is to go green clean and sustainable.
